[Shkelqim_Kajtaz]

Dear all, i have problems chaning my topology every minutes i think i have some trouble with spaning tree can someone help me how to find spaning tree port

[Shkelqim_Kajtaz]

I use s800 series edge switch, yes the spaning tree is activated on rstp mode

here is my logging server

every minutues my topology changes i dont know what heppen

[Jeremy_Gibbs]

Check lag.0.31 and the other lags that have high counters. Do you have spangaurd turned on on the edge ports with adminedge? What are your edge switches?

[Daniel_Coughlin]

That looks like a good place to start.

In EXOS, "show vlan" will help you to identify which ones have STP enabled on them - STP enabled vlans are denoted by the "T" flag.
You can then do "show vlan " and it will show you which ports are being blocked by STP - blocked ports will have a "b" next to them.
"Show port info detail" will then give you further information still about the state of the port and it's configuration.
